INKING MECHANISM.

Original application ied October 25, 1922, Serial No.

8, 1923, Serial No. 673.505.

The invention relates to an inking mechanism or device and among its many useful applications has particularl utility in connection with a machine for endorsing or otherwise marking checks or the like. This application is a division of my application Serial No. 596,728, filed October 25, 1922, for check endorser machine. An examination of the latter mentioned application will aid in a complete understanding of one usefulapplication of the present invention.

My invention contemplates the provision of an improved inking device or mechanism and has for its objects: to provide an inking mechanism composed of few parts simply and. compaotly arranged whereby convenience and accuracy in the operation thereof is insured; to provide an inking mechanism which may be readily and conveniently assembled within or removed `from a check endorsing machine or the like; .to provide an inking mechanism so designed as to prevent the accumulation of a superiiuous quantity of ink ont-he inking roller and in which the continuous feed of the proper amount of ink to the inking roller is definitely effected.

In addition to the general objects recited above, the invention includes among its advantages, such other improvements and advantages in construction and operation as are found to Obtain in the structures and devices hereinafter described or claimed.

In the accompanying drawings, forming a part of this specification, and showing, for purposes of exemplification, a preferred form land manner in which the invention may be embodied and practiced, but `without limiting the claimed invention specifically to such illustrative instance or instances:

Figure 1 is a plan view of a portion of a check endorsing machine or the like, having assembled therein an inking` device or mechanism constituting the preferred embodiment of the invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a view similar to Fig. 2 looking from the opposite side of the machine.

Fig. 4 is a longitudinal vertical sectional view on line 4-1 of Fig. 1.

Fig. 5 is a side elevation of the ink spreader.

Referring to the drawings, 1 and 2 designate a pair of co-eXtending arms which are rigidly secured at their lower ends tothe Renewed December 18, 1926.

frame of the check endorsing machine (not shown) and having pivotally and adjustably mounted in the free ends thereof, by means of stud shafts 3, 3', a' second pair of arms or bracket members 4 and 5. Mounted in suitable bosses 6 and 7 in the free ends of the members 4 vand 5 and extending inwardly therefrom are a pair of supporting trunnions 8, 8. These trunnions through the intermediary of ball bearings (not shown) of which their ends are fashioned to constitute the cones, support the opposite ends of the printing or type roller 10 and provide a substanf tially frictionless bearing construction for the said type roller. The roller 10 is further provided with a removable type plate 11 carrying the fixed type on its outer surface and having a substantially rectangular aperture 12 through which projects the changeable data, contained within the roller 10, to be lprinted on the check, and which data is in alinement with said aperture when the plate 11 is positioned on the roller 10. The check endorsing machine of which the present improvements may constitute a part, is preferably automatic in operation and isiactuated by the check or other piece of paper to ybe -marked by the impression roller 10, the said roller lO'being actuated by the insertion of the check to be marked or endorsed. The particular mechanism cooperating with the inserted check and by which the intermittent rotation of the impression roller 10 is obtained, forms the subject matter of my above mentioned co-pending application and as the same is set forth lin detail therein, will not be further described.

Formed integrally with the inner Surfaces of the members or arms 1 and 5 and suitably positioned thereon, is a. pair of oppositely disposed bosses 13 and 11iV having journaled thereon by means of stud shafts 15 and 16, a pivotally mounted supporting frame 17. The frame 17 is provided with a pair of upwardly extending arms 18 terminating in yokes 18a forming bearings vfor the ends of the shaft 19 of the inking roller 20, the latter being removably secured as by pins 21 for free rotation within said yokes.

The roller 2O is provided with a removable circumferential layer of felt 2()ZL or any preferred ink kabsorbing material. A rearwardly projecting tail portion 22 of the frame 17'terminates in a socketed boss 23 which constitutes a seat for the short plunger 24 bearing against the upper end ot' a coil spring 25. rthe latter is seated in a socket 26 in a rearwardly extending portion ot the trame. i set screw 27 is threaded into the boss 23 of the traine 1T and bears at its lower end against the upper surface of the plunger 24:. lt will be seen by the arrangement described that any desired adjustment ot the 'traine 17 may be effected to bring the inlring roller 2O into the proper cooperating rela-- tion with the type roller 10.

An inl; receptacle 28 is provided, having dependingl arms 29 at either end which are journaled on the stud shafts 15 and 16. `The ends ot the inl; receptacle 28 are slotted as at 30 to provide a removable journal support tor the shaft 31 ot an inl; spreader designated as an entirety by 32. The spreader 32 comprises a plurality ot radially extending ink distributingl pins 33 which, when the spreader is rotated, are immersed in the ink contained in the receptacle 28, and the ink deposited thereon is carried to and deposited by friction-al contact on the roller 2() during operation ot the machine. is best seen in Fig. 1, the radially extending pins 33 of the ink spreader bears a staggered or spiral relation to one another about the hub ot the shaft 3l with the result that the ink carried up from the receptacle 28 is widely distributed in small drops over the inlting pad 2Oa ot the inl; roller 20, and the inl; so distributed is spread by capillary attraction over the entire inlring surface ot such roller. rlhis arrangement insures an even distribution of the ink over the surface 21 and prevents an oversupply ot ink thereto.

The slotted construction 30 permits ready and convenient removal ot the ink spreader 32 trom the inl; receptacle when desired, and the inlt roller 20 may be conveniently removed trom the yolte portions 18a ot' the arm 18 by removing the pins 21 from said yokes.

The ink spreader 82 is held in constant engagement with the inlring roll 20 by means ot a coil spring 34e, seated in and engaging opposed sockets 35, 35 in the inlr receptacle 28 and the rearwardly extending tail portion 22 of the traine 17. This tension may be varied to any desired extent by adjusting a set screw 86 having a threaded engagement in a boss 37 provided at one end of the ink receptacle 28 and bearing at its other end against the iframe 17.

The operation ot' the mechanism above described is as follows:

A check 38 or other slip of paper to be printed or endorsed .is ted by suitable mechanism (not shown) into Contact with the mechanism which actuates the intermittently rotating printing roller l0. The desired .impression is made upon the check by the rotation of the salu printing roller 10 with which said check is in contact and this rotation of the roller 10 is imparted to the inking roller 20 which in turn imparts said rotation to the init spreader 32 by means of the radially extending pins 33 with which the roller 2O is in contact. rlhe various rotations described are maintained as long as the checks or other material to be marl-:ed are fed to the impression roller 10. fitter the type has made the desired impression on the check, it passes around and revolves the inking roller 20 and receives therefrom a resh supply or' ink on its type surface, to be applied to the following check on the next ensuing revolution of the type roller.

rl`he intermittent rotation ot the type roller 10 and inl; roller 2O causes a similar' intermittent rotation ot the ink spreader 32 which feeds and widely distributes a itresh supply of ink to the inking roller, thus insuring at all times adequate and continued ink supply to the type surfaces.

When desired, an ink spreader having a greater or lesser number ot staggered, spirally arranged ink-distributing lingers may be conveniently substituted in the mechanism described by reason ot the slotted journal construction ot the ink receptacle 28.
